Google DeepMind's GenCast is based on diffusion: https://deepmind.google/discover/blog/gencast-predicts-weath...

(Partially) Google Research's/DeepMind's NeuralGCM is based on hybrid models using ODEs and learnt physics: https://www.nature.com/articles/s41586-024-07744-y

Microsoft Research's Aurora on vision transformers: https://www.microsoft.com/en-us/research/blog/introducing-au...

Huawei's Pangu Weather is also a 3D transformer I believe https://www.nature.com/articles/s41586-024-07744-y

I just wanted to highlight that there are multiple approaches in use for the same problem / in the same domain, and GNN does not seem to be the most widely used one.

eperfa | 2 years ago | on: Why did Darwin’s 20th-century followers get evolution so wrong?

(I have no extra knowledge of the topic, just read the article and found it interesting)

You are right that at certain points randomness is emphasised, but I think the main claim of the article is that evolution is not driven purely by random mutations.

The generally accepted theory is that progress is driven by small, continuously occurring changes (mutations), which happen solely due to DNA/RNA transcription errors (random = not influenced by external factors), and this gradually leads to the formation of new capabilities/species.

Instead the article suggests that 1. there are multiple other paths how the DNA is modified, not just by point errors (not just mutations) - examples of this are the TE changes you quoted, but also completely absorbing long pieces of DNA (and potentially entirely new capabilities) from other species, inbreeding, etc. 2. and that external factors influence the frequency of this happening, e.g. by reacting to stress (the process is not purely random)

eperfa | 4 years ago | on: Hungarian journalists and critics of Orbán were targeted with Pegasus

What is being done by Fidesz is definitely not what "most other developed countries" do. I won't be able to discuss all topics, but I'll give you a few examples of the media situation.

There were several businessmen who became extremely wealthy within a very short period, either by working directly for the government (usually with all the typical signs of corruption), or by getting financed directly or indirectly by the government in the form of huge free loans, grants, etc. These businessmen then started buying different media outlets, some of which were 'usual' business transactions, while others were very nasty stories in themselves (the ownership change of the news site Index.hu was probably the biggest scandal). At some point all of these supposedly independent businessmen decided to give away ALL of the media companies they owned for free to a new non-profit entity. This transaction was given a special exemption by the government from all the usual checks and requirements (like antitrust), even though hundreds of media outlets were concentrated in a single entity, which now governs the majority of print newspapers and radio stations. Since this has happened, all of them transfer exactly the same messages - for example look at the following picture to see the front page of the 19 or so county news sites the day before the last election, where the headline says "Both votes for Fidesz!". These used to have independent editorial boards and focused on local news previously.

The state-owned national media holding MTVA (like the BBC in the UK), which of course is supposed to give an unbiased view of the world, also transfers exactly the same messages - there were several scandals where it became public that even senior editors had to send their content for review to Fidesz's people for review, and they got detailed instructions on what and how to say.

Viktor Orban, the prime minister for 10 years, refuses to answer questions or give interviews to any media that is considered to be 'the opposition', even the sites with the highest number of daily readers. At the same time members of the opposition parties are given close-to-0 airtime on the state-owned national channels, and even when they are shown, it is in a negative context.

The national media regulatory body does not check any of the previous issues, but they have been very active for example in revoking the license of one of the last non-Fidesz-friendly radio stations (Klubradio) recently, which also became a scandal.

The work of journalist is made more and more difficult because the state refuses to give information to them or even answer basic questions - for example during the corona virus epidemic, Hungary had by far the least informative site on the topic, yet it was filled with propaganda news. For example to create a chart of the daily cases, journalists had to manually check the site every day and save the currently shown numbers. In order to get a breakdown per county about the cases, they had to submit an official inquiry, where first they said that such data is not available (!), then used all 45+45=90 days to give an answer. Of course the answer only contained the data for the time period when the questions was sent, so it was basically impossible to get up-to-date information.

Viktor Orban still frequently uses the same defence that "they are working in an unfriendly media environment and only try to restore balance", but that is simply not true.

eperfa | 4 years ago | on: Hungarian journalists and critics of Orbán were targeted with Pegasus

It is true that Fidesz, his party, has won 2/3rds of the seats in the Parliament, though they only got 45.2% of the total votes. This victory was in part due to them significantly re-drawing the regions used during the elections to their favour, changing rules for voting from abroad (making it easier to vote from neighbouring regions where most of the people are traditionally their supporters, but more difficult from other parts of the world, where most of the population would like to see a change). It was also helped by using the state to fund and run their own campaign with virtually unlimited amount of money (they were the ruling party in the previous term as well), gradually taking control of all media outlets (especially traditional print and TV ones, further strengthening their base in more rural areas), etc.

Since then they have taken even more control of the media, diverted the majority of EU and state funds to loyal businessmen (a regular gas-fitter became the wealthiest man in the country in a few short years, believed to be the straw man of Orban himself), filled all major positions with their own people (including most recently the high court), created laws directly against the civil society and LMBTQ+ people, stopped most of the funding to towns that have elected politicians from the opposition, taken control of all universities and actively worked on getting rid of CEU (one of the best, independent university, which was criticised due to being funded by George Soros), signed secret business deals for enormous amounts of money with Chinese and Russian interests that will almost certainly never be beneficial for Hungary, etc.

The comparison to Belarus is not correct in the sense that in Hungary violence has not been used (fortunately), but apart from that the governing party has done everything else they can to keep their power and crush everyone else.

eperfa | 5 years ago | on: Babies' random choices become their preferences

"In follow-up experiments, when the researchers instead chose which toy the baby would play with, the phenomenon disappeared entirely. If you take the element of choice away, Feigenson said, the phenomenon goes away."

eperfa | 5 years ago | on: Fasting improves chemotherapy results and protects from side effects: study

Absolutely not a doctor, so no way qualified to give professional advice, but the article states that not everyone followed the diet during all treatments, so they included all patients who complied at least during half of the cases, and the positive results are based on this extended group. This, and the suggested mechanism of why they think the method works, would lead me to believe that it makes sense to try it.

Wish you & your wife strength and all the best.

eperfa | 5 years ago | on: Fasting improves chemotherapy results and protects from side effects: study

Looks like this study was initiated/sponsored by this company, specifically testing the effectiveness on what they call Fasting Mimicking Diet.

https://l-nutra.com/pages/fasting-mimicking-diet

If I understand correctly this is a low-calorie diet, which is easier to follow than a strict water-only diet, but they claim it is equally effective. They recommend it also for healthy individuals, 5 days a month. Does anyone have experience with it?

eperfa | 9 years ago | on: Announcing .NET Core 1.0

I might be missing something here, but does this mean that .NET Framework and .NET Core have diverged, and you need to take extra steps to keep code compatible with both?

The major differences between .NET Core and the .NET Framework: [...] APIs — .NET Core contains many of the same, but fewer, APIs as the .NET Framework, and with a different factoring (assembly names are different; type shape differs in key cases). These differences currently typically require changes to port source to .NET Core.

While I understand the motivation, this at first sight looks like something that will be with us for a long time, and could make life more difficult especially for library authors, who need to potentially target both 'platforms'.

[Disclaimer: haven't used .NET technologies for a very long time and might be horribly wrong here]

eperfa | 9 years ago | on: Show HN: IPsec VPN Server in Docker Container

ZeroTier looks amazing and exactly like what I've been searching for. I'm testing and installing it right now, hopefully we'll be happy users soon.

One minor comment: while reading through the home page the question I first wanted to see answered was 'how do I control who joins my private network', because the technical FAQ says 'Certificates are used instead of access control lists to permit huge networks. An access control list for a network with millions of devices would become unmanageably large.'

I understand this is the technical implementation, but from a user's perspective it actually is an access control list, as on the web interface it is simply a list of IDs which can be approved or declined.

The VPN space really needed a solution like this, congrats for rocking!

eperfa | 11 years ago | on: Hungary Internet tax cancelled after mass protests

Hungary already has a separate telecommunication tax paid after every minute of phone calls and every sent message (SMS or MMS). The telco providers (T-Mobile, Telenor and Vodafon are the three major players here) were supposed to pay this from their own profit without making the customers pay for it, but that is of course not how the market works. The current proposed internet tax would be based on the amount of data transfer.
